MGM Springfield posted a roughly 4.5 percent month-over-month decline in November gaming revenues, the $960 million casino's third full month in operation, the Massachusetts Gaming Commission said.

The commission, MGM Springfield's regulator, on Monday said the casino last month netted $13.3 million from slots, down about 8.5 percent from the $14.6 million recorded in October.

MGM Springfield also recorded $7.8 million in table game revenues in November, a 3.3 percent increase vs. October.

In total, gaming revenues fell almost $995,000, or about 4.5 percent, to more than $21.2 million. Debuting Aug. 24, the casino's gaming revenues have steadily declined over the last three months, with MGM recording $26.9 million in September and $22.2 million in October.

Taxed at 25 percent, MGM Springfield contributed about $5.3 million to the state of Massachusetts in November, the commission said.

MGM Springfield is projected to take a share of profits away from Connecticut's two tribal casinos, Foxwoods Resort Casino and Mohegan Sun.
